x86/alternatives: Print containing function
... in the "debug-alternative" output so that one can find her way
easier when staring at the vmlinux disassembly.
For example:
apply_alternatives: feat: 3*32+18, old: (read_tsc+0x0/0x10 (ffffffff8101d1c0) len: 5), repl: (ffffffff824e6d33, len: 5)
^^^^^^^^^^^^^^^^^
ffffffff8101d1c0: old_insn: 0f 31 90 90 90
ffffffff824e6d33: rpl_insn: 0f ae e8 0f 31
ffffffff8101d1c0: final_insn: 0f ae e8 0f 31
No functional changes.
